Stainless still frame, structure 1.8 x 1.4 m h 1.8 m, 1800 ml extractor.
Size and weight: The frame, the vessels and the pipings is completely built with stainless steel, the total structure has got these sizes: Wide 1.8 m (5.9 feet), Height 1,8 cm (5.9 feet), Deep 1,4 cm (4.5 feet). The Weight of the machinery is 700kg (1543 pounds). For this features we recommend Room sizes of 3x3 m (9.8x9.8 feet) and Height of 2.6 m (8.5 feet).
Main Characteristics: This machine is certified with CE or UL Certified Enclosure, and these are some of the most important technical specifications: Voltage 460 AC-V or 400 AC-V, Frequency 60 Hz or 50 Hz, Installed Power 4.5 kW, Current 6 A.
Configurations: This machine is composed by one or two pumps, one for CO2 and another one for co-solvent, one extraction vessels, two/three separation vessels and separated chiller and heater. It can reach max pressure (Pmax) of 350 bar and max temperature (Tmax) of 85 °C. There are two pressure set-points: the first one is for extraction vessels, and the second one for separation vessels. There are 5 pressure gauges and voltage can be chosen on request.
Carbon dioxide is continually recycled with a close circuit for fluid recirculation. PLC on board in PLC version, the system is connected with internet by an ethernet network connection, it's full automatic and it's equipped with touch screen and it's PED/CE certified or ASME/UL certified.
Pumps: There are two pumps, the most important is the CO2 pump, the carbon dioxide is the principal solvent for the extraction of apolar chemical compounds; and the secondary pump, which is used for the contemporary release in the process of polar or medium apolar co-solvents, useful for the extraction of chemical compounds with different degrees of polarity. At the condition of max pressure this pumps can ensure a CO2 Flow of 12 kg/h, and Co-solvent Flow of 1 L/h.
The extraction process is based on small variations of solvent's (CO2) pressure and temperature. These critical operations are ensured by some heater exchangers, filled by water which is heated or cooled by separated and external Chiller and Heater. Also these components have some technical specifications like:
Extractor volume 1 : 1,5 L
Extraction basket volume 1: 1 L
Separator 1 volume: 0.25 L
Separators 2 & 3 volumes: 1 L
Accumulator volume: 2.7 L
ASME certified safety valve for each vessel in isolated tubing from vessel.
PLC microprocessor Intel i5, PLC version
Compressed air pressure 100 Ψ
Compressed air flow 1 CFM/h
